Low salinity water injection (LSWI) is one of the leading techniques in terms of enhancing oil recovery in sandstone and carbonate formations. Many studies and lab experiments were performed on the LSWI applications. Some studies have pointed out multiple negative observations, while other studies have shown the positive potential of using LSWI in enhancing oil recovery. However, the technology used in LSWI applications is still considered new and more studies need to be performed to figure out new technologies that are low-cost and more efficient. This review paper examines LSWI by analyzing the benefits and drawbacks of employing LSWI in various formations. Primarily, the paper analyzes previous work on LSWI in order to objectively assess the possibility of improved oil recovery and its mechanism. Following that, the study investigates numerous different implementations of the LSWI approach and the leap that has occurred in the oil business. To study the applicability of LSWI, this critical review discusses the experimental and fieldwork that led to the development of low salinity water (LSW) flooding techniques. Upon completion, the article would represent the applicability of LSW flooding in various reservoir conditions, as mentioned in various research studies.
